Coyote Chorus is a DirectX plugin that offers professional-quality chorusing and flanging effects. It has four chorus/flange blocks, each of which allows a very detailed level of control.

Good Points
In addition to the usual controls (delay, range, depth of effect, feedback control) Coyote Chorus also provides control of some unusual parameters:
- a prefilter to restrict the effect to some range of frequencies
- a stereo phase invert control on the low-frequency oscillator (LFO)
- sine, triangle-wave and randomized triangle-wave options for the LFO
- offsetting of the peaks and notches in the frequency response while flanging
Parameter changes are clickless.
